Conda falsely claims noarch/repodata.json.bz2 is required in channels #14965

What happened?
This is no longer true, and for years now conda can't use repodata.json.bz2 at all. Update documentation and error message(s).
As of conda 4.3, a valid channel must contain a `noarch/repodata.json` and
associated `noarch/repodata.json.bz2` file, even if `noarch/repodata.json` is
empty. Use `conda index /tmp/asd`, or create `noarch/repodata.json`
and associated `noarch/repodata.json.bz2`.
